Hi,
This project is to build cyclic on-off programmable timer. In this project user can set ON timer and Off time using keys and 7 segment display. Relay is provided as output, where relay will be remained ON for ON time and it will goes OFF after ON time overs. And Relay will remain Off till Off time overs.
